Abstract (en)

The present specification provides a method for handling a collision between a demodulation reference signal (DMRS) and a channel state information-reference signal (CSI-RS) in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving a DMRS from a base station; receiving a CSI-RS from the base station; and when a collision between the DMRS and the CSI-RS occurs on at least one resource element (RE), puncturing a resource associated with the DMRS, or a resource associated with the CSI-RS on the basis of time domain behavior of the CSI-RS.
